I still think Amazon is doing the right thing.
a) THey put out a note and then contacted the publisher eventually after a day. Given their scale, I would assume it would be necessary to validate the customer complaints before handing off to the publishers.
b) Again, they are just being extra careful about copyrights to the book contents.
c) Do it right and give the best reading experience the first time, otherwise customer are right to complain. I kind of don't like the publish quickly, update frequently model that the author is trying to do. It breaks the book reading experience.
